ZooKernel/Embed/PHP description page
You get lot of allready existing php code and need to use this code with the less modifications possible ? Then this page was made for you :)
On this page you will find everything you have to know to be able to implement your services directly in PHP.
Configure and Install PHP Embed library
First thing you have to get is a fresh and independant php library installed on your system.
Here is a sample configure call to ensure to be able to use the PHP support on your platform :
./configure' '--prefix=/usr/lib/php5.2.10' \ '--host=i686-pc-linux-gnu'\ '--mandir=/usr/lib/php5.2.10/man'\ '--infodir=/usr/lib/php5.2.10/info'\ '--sysconfdir=/etc'\ '--cache-file=./config.cache'\ '--with-pcre-regex=/usr'\ '--enable-maintainer-zts'\ '--with-config-file-path=/etc/php/apache2-php5.2.10'\ '--with-config-file-scan-dir=/etc/php/apache2-php5.2.10/ext-active'\ '--without-pear'\ '--disable-bcmath'\ '--with-bz2'\ '--disable-calendar'\ '--with-curl'\ '--without-curlwrappers'\ '--disable-dbase'\ '--enable-exif'\ '--without-fbsql'\ '--without-fdftk'\ '--disable-filter'\ '--enable-ftp'\ '--with-gettext'\ '--without-gmp'\ '--disable-hash'\ '--without-kerberos'\ '--enable-mbstring'\ '--with-mcrypt'\ '--without-mhash'\ '--without-msql'\ '--without-mssql'\ '--with-ncurses'\ '--with-openssl'\ '--with-openssl-dir=/usr'\ '--disable-pcntl'\ '--disable-pdo'\ '--with-pgsql'\ '--disable-posix'\ '--without-pspell'\ '--without-recode'\ '--disable-shmop'\ '--without-snmp'\ '--enable-soap'\ '--enable-sockets'\ '--without-sybase'\ '--without-sybase-ct'\ '--disable-sysvmsg'\ '--disable-sysvsem'\ '--disable-sysvshm'\ '--without-tidy'\ '--enable-wddx'\ '--with-xmlrpc'\ '--with-xsl'\ '--enable-zip'\ '--with-zlib'\ '--disable-debug'\ '--enable-dba'\ '--without-cdb'\ '--with-db4'\ '--disable-flatfile'\ '--with-gdbm'\ '--disable-inifile'\ '--without-qdbm'\ '--with-freetype-dir=/usr'\ '--with-t1lib=/usr'\ '--disable-gd-jis-conv'\ '--with-jpeg-dir=/usr'\ '--with-png-dir=/usr'\ '--with-xpm-dir=/usr'\ '--with-gd'\ '--without-mysqli'\ '--with-readline'\ '--without-libedit'\ '--without-mm'\ '--with-sqlite=/usr'\ '--enable-sqlite-utf8'\ '--with-pic'\ '--enable-embed'
As you could seen above, there are lot of configure options used. Lots options are not required. Nevertheless, two configure options are required to get a full PHP support in your ZooKernel : --enable-embed and '--enable-maintainer-zts. You should also note that the php library will be installed in the /usr/lib/php5.2.10 directory, as we need a well sperated installation of php to not interfere with your possibly allready installed PHP version.
Once your configure script end with success, you're now ready to compile and install the php embed library, using the following commands :
make
make test
make install
Simple PHP scripts loader
Here is the simplest code snipest ever shared. It was provided here as a sample to load and run php script from a C program :
/** * Filename : test_phpembed.c */ #include <stdio.h> #include <sapi/embed/php_embed.h> #include <zend_stream.h> int main(int argc,char*argv[]){ zend_file_handle script; if(argc<=1){ fprintf(stderr,"Usage: embed filename.php <arguments>\n"); return -1; } script.type=ZEND_HANDLE_FP; script.filename=argv[1]; script.opened_path=NULL; script.free_filename=0; if(!(script.handle.fp=fopen(script.filename,"rb"))){ fprintf(stderr,"Unable to open : %s\n",argv[1]); return -1; } argc--; argv++; PHP_EMBED_START_BLOCK(argc,argv) php_execute_script(&script TSRMLS_CC); PHP_EMBED_END_BLOCK() return 0; }
Compile the code snipest
Now that you get the file test_phpembed.c, you have to compile it before trying to run. You could use the following commands to achieve that compilation process :
gcc -o test_phpembeded.o test_phpembeded.c -c $(/usr/lib/php5.2.10/bin/php-config --includes) gcc -o test_phpembeded test_phpembeded.o $(/usr/lib/php5.2.10/bin/php-config --ldflags) $(/usr/lib/php5.2.10/bin/php-config --libs) -L /usr/lib/php5.2.10/lib/ -lphp5
You should succeed runing the command above, else open a ticket please to inform us that there is issue following those instructions :)
Run the code snipest
The last step to get your PHP embeded in yoru C program is to write a small php piece a .... code :)
cat > info.php <<EOF
<? phpinfo(); ?>
EOF
Here we are, we now run the test_phpembed program to see if it was able to load and run the php script called info.php :
LD_LIBRARY_PATH="/usr/lib/php5.2.10/lib/" ./test_phpembeded /var/www/localhost/htdocs/info.php | less
Note that we have to set the LD_LIBRARY_PATH at runtime as we didn't install the php embed library in a stadard fashion (not in the standard search path - /usr/lib or /usr/local/lib- to ensure that we don't interfer with your allready installed php library). Neevertheless, when ZooKernel will be compiled you only have ot run it once, so you could use a small batch file including this LD_LIBRARY_PATH and other required parameters when you launch your ZooKernel instance (note that firefox do something like that also).
